OK to no longer supports width-only or height-only paper sizes?

The rest of out printing code is not designed for that.

       dev_mode->dmFields |= DM_PAPERWIDTH;
       dev_mode->dmPaperWidth = width;
-    }
-    if (height > 0) {
       dev_mode->dmFields |= DM_PAPERLENGTH;
       dev_mode->dmPaperLength = height;
     }
   }
 
   return printing::CreateDevMode(printer, dev_mode.get());
 }
